What is this?

WATCH ABOVE: A courtroom in Ontario heard testimony that links Michael Sona to robocalls made in the 2011 election campaign. It was the first piece of evidence that links the Conservative campaign in Guelph to the controversial calls. Jacques Bourbeau explains.

GUELPH, ONT. – They were longtime Conservative co-workers who looked at politics the same way and wanted “to see this country do better.”

It was a day that saw another former Conservative staffer, Rebecca Docksteader, point the finger at Sona for taking “full credit” for a scheme to mislead Liberal voters on election day 2011 – even though she admitted he was often guilty of animated storytelling.

“I wasn’t sure if I could take the story seriously or not,” she said. Docksteader told her former boss, Conservative MP Chris Warkentin, about the conversation after Sona’s name was made public in February 2012.

Three more Conservative staffers are expected to testify Thursday.

‘It’s working’

Calls falsely said to be from Elections Canada were sent out to more than 6,700 people on May 2, 2011, telling non-Conservative supporters their polling stations had changed.

It was later revealed the calls came from automated firm RackNine Inc., registered under the fake name Pierre S. Jones, and that a Pierre Poutine had used a burner cellphone to call the company.

Sona, 25, is charged with “wilfully preventing or endeavouring to prevent an elector from voting.” If convicted, he faces up to five years in prison.

Prescott, who was the deputy campaign campaign manager for Conservative candidate Marty Burke, also admitted on the stand that he withheld information from investigators for almost two years.

He also recalled specific information about Sona he had never before revealed in interviews.

Prescott testified that Sona emerged from his cubicle in the early morning hours of May 2, 2011 looking “euphoric,” and saying ‘It’s working.’
